That's the only (but significant) difference in the frame (aside from the paint scheme, like you said). Geometry is identical. The wheelset is different on the Race Disc model for '06 - they switched to DT Swiss hubs. Pro model is the same build. I'd think that for '07, there won't be any major changes in the frame since they just made the big switch to carbon. The design has been refined quite nicely at this point.
